Hello Richard,

We deliver a corresponding MD5 checksum (aka "hash") file with every 
file (BWF, WAVE, MP3, scanned metadata, etc.) that we deliver to our 
clients.  The delivery and use of MD5 checksums should be considered 
archival "best practice", as it is the only way to be absolutely sure 
that a digital file has not been corrupted over time, or that there 
were no errors when copying or moving a digital file.

If you are on Windows...

We tested the many, MANY checksum generators available as freeware
and shareware, and we finally settled on "Fastsum" (www.fastsum.com).
It has a VERY professional user interface which allows you to 
either generate checksums for batches of files, or validate batches
of files.  We have Fastsum loaded on all of our capture and editing
stations, and use it many times daily.  It has performed flawlessly
with no quirks or bugs, and the Fastsum customer service (via email)
is very responsive.

Fastsum is highly configurable, from generating individual checksum
files for every target file (what you want to do), to generating a 
single file that contains individual checksums for every file (this 
is the default setting).

Initially, I was disappointed that Fastsum didn't have a means to 
call it from another program.  However, the Fastsum user interface
makes things so simple that this has not been a workflow issue, even
when processing hundreds of hours of audio a week.  Of course, if 
you want a checksum generator that can be incorporated into your
software automation, there are plenty of options (we haven't done
a systematic evaluation of these).

The free version of Fastsum (and I think the home version, too) adds 
some text advertising to each MD5 checksum file.  The "Enterprise" 
version (all of $25 for one license) allows you to turn off the 
advertising.  I consider this money well spent (we purchased one of 
the multi-user license packages).  Usual disclaimer: we have no 
relationship with Fastsum and do not benefit in any way from the 
sales of Fastsum software.

Slightly off topic... we are experimenting with running an MD5 
checksum on just the PCM portion of the WAVE/BWF file, so that we 
can edit the WAVE-RIFF and bext chunks and insure that there 
was no corruption to the PCM audio in the process.

Subject: [ARSCLIST] MD5 Hash Generators


I am starting to generate an MD5 hash of the files that I deliver by 
ftp and was wondering which MD5 hash generators are popular.

I found a pretty neet one-file-at-a-time applet that will generate a 
companion ".md5" file which is good for my workflow. www.drnaylor.co.uk

I would like a batch generator that would place each hash into a 
separate text file with the complete filename and the extension md5 added.

Any suggestions?

Of course, I'd prefer freeware as I don't think this is an 
extra-charge service.

Cheers,

Richard
